I am on Ubuntu 13.10 desktop
16GB ram
asus sabertooth 990fx r2.0 motherboard
amd 8346 cpu
nvidia gtx650 video card

Since upgrading to Ubuntu 13.10 audio no longer works in KVM.
Checking SYSLOG I found this error being logged:

Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21 Analog] alsa-source.c: ALSA woke us up to read new data from the device, but there was actually nothing to read!
Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21 Analog] alsa-source.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21 Analog] alsa-source.c: We were woken up with POLLIN set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
